Introduction
California’s rising temperatures have made heat illness one of the most serious workplace hazards—especially for outdoor workers in construction, agriculture, delivery, landscaping, and warehousing. When employers fail to protect workers from extreme heat, they can be held liable under both workers’ compensation and employment laws.
At Employees First Labor Law (EFLL), we help workers who suffer from heat-related injuries or retaliation for speaking up about unsafe working conditions. Here’s what every California employee should know.
Understanding Heat Illness in the Workplace
Heat illness occurs when your body can’t properly cool itself, leading to conditions like:
- Heat exhaustion (fatigue, nausea, dizziness)
- Heat cramps (painful muscle spasms)
- Heat syncope (fainting)
- Heat stroke (life-threatening, medical emergency)
Even indoor workers—such as kitchen staff, factory workers, or warehouse employees—can suffer serious heat injuries if employers fail to maintain adequate ventilation or cooling.

Workers’ Compensation for Heat Illness
If you become ill or injured due to excessive workplace heat, you may be entitled to workers’ compensation benefits, including:
- Medical treatment for heat illness, dehydration, or related complications
- Temporary disability benefits while you recover and can’t work
- Permanent disability compensation if the heat injury causes lasting damage
- Vocational rehabilitation if you can’t return to your prior job
To qualify, you must show that the injury arose out of and occurred during employment—which is usually straightforward for outdoor or high-temperature work settings. Employers and insurers sometimes dispute claims, arguing the illness was “personal” or caused by pre-existing conditions. EFLL fights those denials with medical and factual evidence to prove work-related causation.
Employer Liability Under California Employment Laws
California law requires employers to protect workers from heat hazards. Failure to do so can trigger liability under several legal theories:
1. Cal/OSHA Heat Illness Prevention Standards
Employers must:
- Provide shade and potable drinking water
- Allow cool-down breaks when temperatures exceed 80°F
- Implement heat illness prevention training and emergency plans
Failure to follow these standards can lead to Cal/OSHA penalties and evidence of negligence or willful misconduct in related civil or administrative claims.
2. FEHA & Retaliation Protections
Employees who report unsafe working conditions, refuse to work in dangerous heat, or request accommodations for medical conditions are protected from retaliation under:
- Labor Code §6310 (prohibits retaliation for reporting safety violations)
- Labor Code §1102.5 (California Whistleblower Act)
- FEHA (if heat exposure worsens a disability or medical condition)
If an employer fires, demotes, or disciplines an employee for asserting these rights, EFLL can pursue a retaliation or wrongful termination claim in addition to any workers’ comp benefits.
Dual Claims: Workers’ Comp and Employment Law
Many employees don’t realize that a single incident—like collapsing from heat stroke—can give rise to two separate cases:
| Type of Claim | What It Covers | Who’s Liable |
|---|---|---|
| Workers’ Compensation | Medical bills, lost wages, permanent disability | Employer (no fault required) |
| Employment Law / Retaliation | Wrongful termination, retaliation, emotional distress, punitive damages | Employer and individual managers (if misconduct involved) |
EFLL frequently handles dual claims, ensuring injured workers receive full compensation from both systems.
What to Do If You Suffer from Heat Illness at Work
- Seek immediate medical care — heat illness can worsen rapidly.
- Report the injury to your employer in writing as soon as possible.
- Document conditions (temperature, lack of shade, breaks denied, etc.).
- Contact EFLL before signing anything from your employer or insurer.
Our attorneys can evaluate whether you have workers’ compensation, retaliation, or safety violation claims, and pursue maximum recovery under all applicable laws.
Protecting California Workers in the Heat
Employers have a legal and moral duty to keep their workers safe. When they cut corners on heat protection—or punish those who speak up—they break the law. EFLL stands ready to fight for employees exposed to dangerous working conditions anywhere in California.
